In Chapters 2 and 3, we explained how diversity may assist evolution by making very slight mutations of the population.  Diversity is available when the Excel interface is used, and it may also be applied to programs which call GALIB32.DLL.  It is set by the SetDiversity function (refer to Chapter 8).  Diversity is only available for continuous chromosomes made by MakeChromosome, and it is not available with chromosome pools.
